Recently updated my HTPC box with Windows 8. The ASRock A780GMH Motherboard's onboard video wouldn’t play nice with the new operating system so I purchased and installed an ASUS GT520 video card. I completely uninstalled the old ATI Radeon HD 3200 drivers and used Guru 3D Driver Sweeper for good measure. Installed the new card and the most recent drivers downloaded from the GeForce website (v310.70). New card worked flawlessly...for about 45 minutes. Then starting displaying flickering green and pink squares randomly all over the screen.
Checked the GPU temperature with Speedfan--it is hovering at about 62C, well under the max allowed 102 degrees.
Checked the power requirements for the card. Minimum required wattage is 300 according to GeForce's website: http://www.geforce.com/hardware/desktop ... ifications
. I'm packing a 300W SeaSonic SS-300ES, so technically should be ok--if only just barely.
Here’s the rest of the hardware setup:
AMD Phenom II X3 2.5GHz
Kingston HyperX 8GB (4 x 2GB)
Western Digital Green 500GB SATA 3.0Gb/s HD
Mushkin 120GB SATA III SSD
LG Black Blu-ray/HD DVD-ROM
Dell S2309 Monitor (DVI) + Samsung TV (HDMI)
Any ideas on what might be causing my problem? Is it probably the PSU? Or is there another culprit I’m overlooking? Other troubleshooting steps I can take to identify the source of the problem?
Thanks in advance for your input.
